Three more people have been convicted in a nearly $3 million health care fraud case involving Houston and Dallas-area companies.

Prosecutors say unlicensed doctors were recruited to treat patients at their homes and then wrongly bill Medicare.

A federal judge in Dallas on Wednesday convicted Godwin Umotong and Comfort Gates of Houston of conspiracy to commit health care fraud and health care fraud. A third person - Vagharshak Smbatyan of Grenada Hills, Calif., - was convicted of making a false statement to an agency.

All will be sentenced in July and face penalties ranging from five to 10 years per count.
